Description

The health and ecological effects of micropollutants such as PFAS chemicals require a glidepath of how treatment solutions can be implemented. This presentation will detail the importance of initial sampling and how PFAS specific analytical tools such as PFluorensics® can be used to deduce likely sources and character. Remediation requires a bottom-up approach where solutions are scoped based on the level and complexity of the treatment required. This means for some sources, simple coagulation and sedimentation strategies using propriety products such as PerflourAd®. For highly concentrated PFAS sources, such as landfill leachates, treatment can be supplemented with Foam Fractionation and Electro-Oxidation processes. On wastewater treatment works, the application of Granular Activated Carbon is a typical template solution. This presentation will detail the importance of pre-treatment to minimise competing reactions and the benefits of Rapid Small Scale Column Testing (RSSCT) in selecting the most appropriate media. In addition, the integration of novel PFAS specific medias such as modified Bentonite Clay based media and Ion Exchange Resins. Furthermore, design assurance through Pilot Testing and the application of digital tools to forecast media changeover frequencies shall be discussed.
